[0027] The present utility model will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present utility model is not limited to this embodiment.

[0028] As Figure 1 、 Figure 2 shown, the present utility model is a novel plug-in film structure, including a rotating motor 1.

[0029] It should be pointed out that although the present utility model uses a rotating motor as the driving unit, as an alternative power source, other driving units in the prior art can also be used, such as screw drive, belt drive, chain drive, etc.

[0030] Furthermore, as Figure 1As shown in the figure, the gear mechanism 2 of the present utility model includes a transmission gear 21, a rotating column 22 and a magnetic block 23.

[0031] Further, as Figure 1 shown in the figure, in the above structure, in order to maintain the structural integrity of the rotating column, the rotating column 22 and its gear 221 are integrally formed structures; mounting grooves 222 with the same number as the magnetic blocks 23 can be provided on the top of the rotating column 22, and the magnetic blocks 23 are correspondingly placed in the mounting grooves 222; furthermore, the present utility model further includes a magnetic block cover plate 4, and the magnetic block cover plate 4 is buckled on the top of the rotating column 22, so that the magnetic blocks 23 can be prevented from accidentally falling out.

[0032] As a preferred technical solution, the tooth ratio between the rotating gear, the transmission gear and the gear of the rotating column of the present utility model can be adjusted, so as to realize the slow rotation of the rotating column, and make the pattern effects such as starry sky / star river / planet projected by the film more conform to space.

[0033] Further, as Figure 1 shown in the figure, the film mechanism 3 of the present utility model includes a tray 31, a magnetic attraction component 32 and a film component 33. The film component 33 is arranged in the magnetic attraction component 32, and the magnetic attraction component 32 is movably arranged in the tray 31; during magnetic attraction connection, a plurality of the magnetic blocks 23 are magnetically attracted to the magnetic attraction component 32, and when the rotating motor 1 rotates, the magnetic attraction component 32 and the film component 33 rotate synchronously.

[0034] It should be noted that the tray 31 of the present utility model is provided with a cavity 311, and the structure formed by the combination of the magnetic attraction component 32 and the film component 33 is arranged in the cavity 311.

[0035] Further, as Figure 1 shown in the figure, the magnetic attraction component 32 of the present utility model includes a fixed seat 321 and a magnetic ring 322. The bottom of the fixed seat 321 is provided with an annular groove, the magnetic ring 322 is embedded in the annular groove, the film component 33 is arranged in the fixed seat 321, and the fixed seat 321 is movably arranged in the tray 31; wherein, when the fixed seat 321 is magnetically connected, a plurality of the magnetic blocks 23 are magnetically attracted to the magnetic ring 322.

[0036] As a preferred technical solution, the magnetic ring in the present utility model is an iron sheet, and the iron sheet is fixed in the annular groove at the bottom of the fixed seat by an embedded connection method, which can effectively prevent the iron sheet from accidentally detaching from the annular groove.

[0037] Of course, the magnetic ring of the present utility model can also be replaced with other materials that can generate magnetic attraction connection in the prior art.

[0038] Furthermore, as Figure 1 shown, the film component 33 of the present utility model is composed of a film seat 331, a film cover 332 and a film sheet 333. The film sheet 333 is arranged in the film seat 331, and the film cover 332 is covered on the top of the film seat 331; wherein, the film seat 331 is installed in the fixed seat 321.

[0039] As a preferred technical solution, a film placement position is provided in the film seat of the present utility model, and the film sheet is arranged in the film placement position to prevent the film sheet from shaking; in addition, the film cover is press-fitted with the film seat to ensure that the film sheet is not easily oxidized by external air.

[0040] Furthermore, the film seat of the present utility model can be installed in the fixed seat by a movable connection method, such as existing movable connection methods like snap connection and interference fit connection.

[0041] Furthermore, as Figure 1 Figure 3 Figure 4 shown, in order to enable the magnetic attraction component 32 to rotate normally in the tray 31, an activity gap 100 is provided between the fixed seat 321 and the tray 31 of the present utility model.

[0042] It should be noted that, as Figure 1 shown, a tray base 34 is also provided in the present utility model. The tray base 34 is snap-fitted to the bottom of the tray 31, and a cavity that can accommodate the magnetic attraction component 32 is formed by the tray base 34 and the cavity 311 of the tray 31. After magnetic attraction connection, the magnetic attraction component 32 of the present utility model rotates within this cavity.

[0043] As a preferred technical solution, the magnetic attraction component of the present utility model can be installed in the above-mentioned cavity by a movable connection method such as snap connection and interference fit or other existing movable connection methods.

[0044] Even further, as Figure 1 、 Figure 3 、 Figure 4As shown, the active gap 100 referred to in the above structure is to ensure that after the magnetic ring 322 of the magnetic attraction component 32 is magnetically connected to the magnetic block 23, the magnetic attraction component 32 can rotate normally driven by the rotating column 22, so that the film sheet 333 in the film component 33 rotates. For this purpose, an active gap 100 is provided between the periphery of the fixed seat 321 of the magnetic attraction component 32 and the cavity, that is, the outer diameter of the fixed seat is smaller than the inner diameter of the cavity. In this structure, when the magnetically connected magnetic attraction component 32 rotates, the active gap 100 ensures that the fixed seat 321 does not rub against the inner side wall of the cavity formed by the tray 31 and the tray base 34 during rotation, and normal rotation can be achieved. Of course, it can also be understood that the magnetic attraction component has a certain activity space in the cavity formed by the tray and the tray base.

[0045] It should be noted that in order to enable the film sheet to project normally, the rotating column, fixed seat, magnetic ring, film seat, film cover, and film sheet of the present invention are all coaxially arranged; further, the rotating column, magnetic block cover plate, fixed seat, magnetic ring, film seat, film cover, and tray base are all hollow structures.

[0046] As a preferred technical solution, it is previously pointed out that the magnetic attraction component of the present invention can be installed in the cavity of the tray by means of movable connections such as snap fit and interference fit. Therefore, in one embodiment, the present invention can be equipped with multiple magnetic attraction components, and different magnetic attraction components have film sheets with different images. By replacing the magnetic attraction components, the user can project different images, increasing the experience and interest of the present invention.

[0047] Of course, since the film seat of the film component of the present invention can be connected to the fixed seat of the magnetic attraction component by existing movable connection methods such as snap fit connection and interference fit connection, therefore, in another embodiment, only multiple different film components can be equipped. When the user wants to replace different projection images, the film component can be directly replaced.

[0048] As Figure 2 shown, on the basis of the above new plug-and-play film structure, the present invention also provides a projection lamp having this structure. Specifically, the projection lamp includes:

[0049] A movement mechanism frame 4, the gear mechanism 2 and the film mechanism 3 are respectively arranged in the movement mechanism frame 4;

[0050] A light emitting mechanism, the light emitting mechanism includes a light source 5, a condenser cup and a lens 6. Among them, the condenser cup and the lens 6 are sequentially arranged on one side of the illumination surface of the light source 5;

[0051] A focusing mechanism 7, the focusing mechanism 7 includes a lens 71, and the lens 71 can move along its axis direction to adjust the focal length;

[0052] The movement frame 4 is provided with a slot 411, and the film mechanism 3 is movably inserted into the slot 411.

[0053] Further, as Figure 2 shown, the movement frame 4 of the present utility model includes an upper frame body 41 and a lower frame body 42 which are snap-connected to each other. The lower frame body 42 is provided with a tube sleeve 421. The light source 5 is located at the bottom of the tube sleeve 421. The condenser cup and the lens 6 are sequentially arranged in the tube sleeve 421. The tube sleeve 421 is sleeved in the rotating column 22. The slot 411 is arranged on the upper frame body 41, and the focusing mechanism 7 is connected to the upper frame body 41.

[0054] Further, as Figure 2 shown, the present utility model further includes a condenser seat 8 which is also arranged in the tube sleeve 421 and is used for carrying the condenser cup.

[0055] It should be noted that, as Figure 2 shown, the tube sleeve 421 of the present utility model is a hollow structure and is coaxially arranged with the rotating column 22.

[0056] In order that the sleeved tube sleeve does not affect the normal rotation of the rotating column, there is a gap between the tube sleeve and the rotating column, that is, the outer diameter of the tube sleeve is smaller than the inner diameter of the rotating column.

[0057] In addition, as Figure 2 shown, in order to protect the lens 6 in the light-emitting mechanism, the present utility model further includes a lens cover 9. Specifically, a placement groove for the lens is formed at the periphery of the top of the tube sleeve 421. The lens 6 is arranged in the placement groove, and the lens cover 9 is snapped onto the top of the tube sleeve 421 to protect the lens 6.

[0058] Furthermore, as Figure 2 shown, the tray 31 of the present utility model is movably inserted into the slot 411. After the tray 31 is completely inserted into the slot 411, a plurality of magnetic blocks on the rotating column 22 will be magnetically connected to the magnetic ring (iron sheet) in the fixed seat, that is, the plurality of magnetic blocks will firmly adsorb the magnetic component.

[0059] Correspondingly, a round hole is formed at the bottom of the slot, and the position of the round hole corresponds to the cavity formed by the aforementioned tray base and the tray cavity.

[0060] Further, as Figure 2As shown, the focusing mechanism 7 of the present utility model further includes a focusing base 72, a clamping seat 73 and a nut 74. A mounting hole 412 is provided at the top of the upper frame body 41. The nut 74 is arranged in the mounting hole 412. The lens 71 is connected to the clamping seat 73, and the clamping seat 73 is installed in the focusing base 72. The inner side wall surface of the nut 74 is provided with internal threads, and the outer side wall surface of the lens 71 is provided with external threads that cooperate with the internal threads.

[0061] It should be noted that since the lens is installed in the clamping seat, and the clamping seat is installed in the focusing base, through the threaded connection between the lens and the nut, when the focusing base is rotated, the lens can move up or down relative to the nut along its axis, thereby changing the focal length and realizing the adjustment of the clarity of the projected image.

[0062] Furthermore, the present utility model should also have a housing 101. As an embodiment, Figure 5 It is presented that the housing of the present utility model is spherical. In fact, the housing can be of any shape. In addition, an opening 1011 is provided on the housing 101, and this opening 1011 corresponds to the position of the aforementioned slot, and is used for inserting the tray of the film component.

[0063] Furthermore, as Figure 3 、 Figure 5 shown, the present utility model is also provided with a base 75, and this base 75 covers the top of the housing 101. In addition, the focusing base 71 is movably connected to this base 75.

[0064] As Figure 5 shown, in addition to the above-mentioned housing 101, a base 102 can be further added to the housing 101. The base 102 is provided with a pair of support arms 103, and this pair of support arms 103 are respectively rotatably connected to both sides of the housing 101. In this way, the present utility model can realize the adjustment of different projection angles.

[0065] In order to further enrich the functions of the present utility model, as a preferred technical solution, as Figure 5 shown, the present utility model can also be provided with a speaker 104 inside the housing 101. While projecting an image, music is synchronously played through the speaker to further create a better atmosphere.

[0066] It should be noted that the present utility model has a control circuit and a battery that can be charged and discharged in a cycle; further, the functions of this control circuit are the same as those of the prior art. For example, it is used to control the startup or shutdown of the present utility model, the startup or shutdown of the rotating motor, etc.

[0067] Furthermore, the basic optical path of the present utility model is:

[0068] Light source - Condensing cup - Lens - Film - Lens.

[0069] Embodiment

[0070] When using the present utility model, insert the tray along the opening of the housing into the slot. When the tray is completely inserted into the slot, several magnetic blocks at the top of the rotating column will magnetically connect with the magnetic ring (iron sheet) at the bottom of the fixed seat. Since the magnetic component has a certain moving space in the cavity formed by the tray and the tray base, after the magnetic connection, the position of the magnetic attraction component is relatively fixed. At this time, start the present utility model, the light source is lit, the rotating teeth of the rotating motor rotate, and then drive the rotating teeth of the rotating column through the transmission teeth, so that the rotating column rotates synchronously. Further, several magnetic blocks installed at the top of the rotating column rotate synchronously. Since several magnetic blocks are magnetically connected with the magnetic ring (iron sheet) of the magnetic component, the magnetic component rotates synchronously, realizing the synchronous rotation of the film component installed on the magnetic component, and finally making the image projected through the lens rotate.

[0071] In addition, the user can rotate the focusing seat to move the lens up and down, so as to adjust or clearly project the image.

[0072] Finally, as described above, the user can obtain different projected images by replacing the magnetic component or the film component.

[0073] For those skilled in the art, various corresponding changes and deformations can be given according to the above technical solutions and concepts, and all these changes and deformations should be included in the protection scope of the claims of the present utility model.
